The beyerdynamic AT 1350 A is a closed, dynamic headphone for the use with audiometers. It is used for aural-acoustic investigations and measurements. Due to the closed design of the headphone, ambient noise is efficiently attenuated. The efficient Tesla transducers ensure a very good reproduction of the measured results.

The right/left identification with coloured rings meets the standards. The comfortable, replaceable ear pads and the flexible headband ensure ultimate comfort and an absolutely secure fit. The pivoting ear cups (90°) allow listening with one ear and the supplied bag ensures easy transport.

The single-sided, straight connecting cable comes with bare ends
